Autonomous Flight Mode Recovery After Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilot workload and situational awareness are compromised during and after automated collision avoidance maneuvers in aircraft systems, as pilots must manually restore autonomous operation, increasing the risk of errors and deviations from the original flight path.
Innovation Solution
The system autonomously identifies and records the original operating mode before entering collision avoidance mode, dynamically determines viability upon exiting, and automatically reinitiates the original mode or transitions to a viable alternative mode based on current aircraft status, reducing pilot workload and maintaining flight path consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pilots manually restore autonomous operation after collision avoidance maneuvers, then the system maintains operational control, but pilot workload increases and situational awareness deteriorates
Solution Approach 1:
The flight control system automatically detects when collision avoidance mode terminates and self-initiates restoration of the original autonomous operating mode without requiring pilot intervention. The system monitors its own state and autonomously transitions back to the pre-collision mode, effectively serving itself to reduce pilot workload while maintaining operational control.
Solution Approach 2:
The system identifies and stores the original autonomous operating mode before entering collision avoidance mode. By preparing the restoration sequence in advance and maintaining awareness of the original mode settings, the system enables automatic recovery without requiring pilots to recall or reconfigure flight parameters after the maneuver.
2Reliability
If the system automatically reinitiates the original autonomous operating mode after collision avoidance, then flight path consistency is maintained, but system complexity increases
Solution Approach 1:
The system identifies and stores the original autonomous operating mode parameters before entering collision avoidance mode. By capturing the original mode state in advance and maintaining it in memory, the system simplifies the recovery process to a simple restoration operation rather than requiring complex real-time analysis or pilot input, thus maintaining flight path consistency without excessive complexity.

AI summary
Methods and systems are provided for autonomous vehicle operation for collision avoidance. One method involves identifying an autonomous operating mode and one or more settings associated with the autonomous operating mode prior to entering an autonomous collision avoidance mode in response to an output from a collision avoidance system, and after entering the autonomous collision avoidance mode, automatically restoring autonomous operation upon deactivation of the autonomous collision avoidance mode. For example, the autonomous operating mode may be automatically reinitiated based on the current vehicle status using the one or more settings in response to deactivation of the autonomous collision avoidance mode when it is determined that the autonomous operating mode is viable based on a relationship between a current vehicle status and the one or more settings associated with the autonomous operating mode.
